STUFFING-BOX GLAND Specification of Letters Patent.

Patented Nov. 6, 1906.

. To all whom it may con/cern).-v

Be it known'that I, WALTER A. BUNCH, a citizen of the 4United States, residing at Chattanooga, in thei county of Hamilton, State of Tennessee, have invented certain new and useful Improvements in Stuffin -BOX Glands; and I do hereby declare the folI wing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same.

This invention relates to separable stuffing-box lands.

One o ject of the invention is to provide a stuling-box gland of two separate pieces, whereby the gland may be readily attached or detached from a piston or pipe upon which it-may be located.

4Another object of the invention resides in the provision of an exceedingly simple, inexpensive, durable, and eflicient gland of the character stated.

.With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, pro ortion, size, and minor details may be ma e within the scope or the claims Without departing from the spirit or sacrificing any oI the advantages or the present invention.

In the drawings, Figure 1 is a side elevation of the gland. Fig. 2 is a top plan view.

Fig. 3 is a transverse vertical section of thel gland. Fig. 4 is an inner side elevation of one member of the gland. Fig. 5 is an inner side elevation of the other member of the gland. Fig. 6 is an end elevation of one member of the gland. Fig. 7 is an end elevation ofthe other member` or the gland.

Referring now more particularly to the accompanying drawings, the reference characters 1 and 2 indicate ears designed to be iitted one upon the other. Formed upon one side of each ear 1 and 2 is a semicircular stem 3 and 4, respectively. It will be seen that the semicircular stem 3 is formed directly upon one face of the ear 1, while the semicircular stem 4 is formed directly upon the shoulder 5 of the ear 2, which has its opposite edges beveled, as at 6. This shoulder 5 is provided `embrace the correspondingly-bevele with a semicircular notch 7, which corresponds to the semicircular formation of the stem 4 and which two latter elements are arran ed in alinement with the circular end 8 of t e slot 9, formed through one side edge of the ear 2, the edges or the slot 9 being'in direct alinement with the beveled edges 6 or the shoulder 5 and also beveled at its under I edge, as at 10, in a direction opposite to the bevel of the edge 6 of the shoulder 5. These beveled edges 10 ot the slot 9 are designed to ed es 11 of the shoulder 12, formed on the earg 1, While the beveled ed e 6 of the shoulder 5 of the ear 2 is designe to receive the beveled edges 13 of the slot 14, formed through'one side of the ear 1 in alinement with its semicircular stem 3. It will thus be understood that the slots 9 andV 14 of the respective ears are formed through corresponding sides thereof and are disposed for alinement with each other, both slots being the same in formation, save that their beveled edges are reversed with respect to each other. It will also be seen that the shoulder of the respective plates of said ears are upon op osite sides with respect to each other an when the ears are assembled for the formation of a circular bearing therebetween and their corresponding semicircular stems 3 and 4 that the ears and their stems are interlocked with their shoulders in alinement- With the outer face of the opposite ears;

In order that my invention will be more readily understood in its application, I have illustrated in the accompanying drawings a view showin the association of the gland with the stu ng-box. In other words, the reference character a, designates one end of a cylinder provided with a stufling-box b, in which is itted one end of a shaft c. Surrounding the shaft withinthe stuffing-box is a suitable stuffing or packing material d. The

that" semicircular projections 3 and 4, forming the l the alining erforations 15 and 16 of the ears 1 and 2 an connected in any suitable manner with the cylinder-head al that the glandloc ears 2 and 3 cannot become disengaged from their interlocked position with relation to each other. What is claimed isl. A stuIing-boX gland comprising two separable sections each provided with ears adapted to lie one upon the other when the sections are iitted together7 said ears being provided with oppositely-disposed inwardlydirected transverse slots; a sernicircular stem formed directly upon the under face and a shoulder formed upon the upper face of one of said ears a shoulder formed upon the lower face of the opposite ear in :alineinent with said upper shoulder; and a semicircular stern formed upon the lower face of said lower shoulder, said shoulders being adapted to fit in the corresponding slots, to hold the sections interloeked.

2. A stuHing-box gland comprising two separable sections each provided with ears adapted to lie one upon the other when the sections are fitted together7 said ears being provided with oppositely-disposed inwardlydirected transverse slots formed intermediate the ends thereof and having oppositelybeveled edges; a seinieircular stein formed directly upon the under face and 4a shoulder formed upon the upper face of one of said ears7 a shoulder formed upon the lower face of the op osite ear in alinement with said upper shoul er; and a seniicireular stem formed upon the lower face of said lower shoulder, said shoulders having their edges oppositely beveled and being adapted to iit in the corresponding slots to hold the sections interlocked.

In testimony -whereof I aHiX my signature -in presence of two witnesses.
